A Russian Antonov military cargo plane crashed killing all 12 crew members

An ageing Russian military cargo plane has crashed, killing all 12 people aboard, officials said.

The Federal Investigative Committee said the An-22 plane was on a flight from the south-western Voronezh region to the Tver region north-west of Moscow when it crashed in the Tula region, about 120 miles south of Moscow.

It said that along with the crew piloting the Antonov, the giant four-engined turboprop aircraft was also carrying another crew to the Migalovo military airbase in the Tver region.

The cause of the crash was not immediately determined.

The An-22, which was designed in the 1960s, has a payload of 60 metric tons and is capable of airlifting about 300 troops. Only a handful are still in service with the Russian air force. The plane that went down on Tuesday was built in 1974.
